He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

I am the master of a certain dark guild.

Including me, there are only 10 other consistent members in this guild. However, all of them are like daughters to me… is what I think.

Since this is a dark guild, we act without standing out too much. However, it seems like everyone has been acting a bit too weird recently.

They’re acting really weird… eh? What? [Presenting me the whole world]?
